This work reports the preparation and crystal structure of a trihydrate of paracetamol. Crystals were grown by slow cooling of an aqueous solution of paracetamol to 08C. Single-crystal X-ray diffraction shows that the trihydrate crystallizes in the orthorhombic crystal system, space group Pbca, Z ΒΌ

ABSTRACI Erlose [p-o-fructofuranosyl O-o-o-glucopyranosyl-(l + 4&o-glucopyranoside] trihydrate, r&Ha, 0,,.3HaO, M, = 558.48, is orthorhombic, P2,2,2, with a = 31.164(7), b = 13.111(5), c = 11.636(5) A, and Z = 8. The structure was solved by direct methods, and refined to R = 0.035 for 3926 observed
## Abstract The crystal synthesis and structure of a new organic monohydrogenmophosphate (3,4βCl~2~βCH~2~C~6~H~3~NH~3~)~2~HPO~4~Β·2H~2~O are reported. This compound crystallizes in the monoclinic P2~1~/n with a = 9.081(7) Γ , b = 6.501(5) Γ , c = 35.423(12) Γ , Ξ² = 91.09(5)Β°, V = 2090.9(2) Γ ^3^, and Z
